What it feels like
When mornings/evenings and indoor AC differ a lot, you feel the day’s length more than the number.
Rain changes how you move, and wind makes the same temperature feel much harsher.
When it tends to fit
- • If you’ll walk a lot and you’re sensitive to wind or rain, cooler/drier conditions tend to fit better.
- • For photo-and-walk trips, sunny days usually matter more than the exact temperature.
- • If you want to keep fatigue low (kids/family trips), avoiding peak midday heat helps.
When it may not fit
- • If you struggle with humid heat, some seasons can feel tiring even when the numbers look similar.
- • In rainier periods, “walking as planned” can be harder—tight itineraries may not fit well.
What people usually wear
Not a single “correct outfit”—just common choices that cover most situations.
- • 🧩 Key idea: summer comfort is driven by the **heat index**, and spring can be volatile with **thunderstorms and gusty winds**.
- • 🥵 Jun–Sep: breathable, sweat-friendly fabrics help. A thin layer can be useful indoors with strong A/C.
- • 🌩️ Mar–May: storms can arrive quickly—plan for brief heavy rain and shifting wind.
In the end, it often depends on one or two conditions you care about most.
